The real evolution creationism debate?

Your question about a deity creating the first cell presumes that there are deities. While there is no concrete evidence at the moment about how the first events leading to life happened, there is no physical evidence whatsoever for the existence of any deities. Thus, to show that a deity may have created the first life form, one must first show that there are deities. This demonstration must include a lot of positive physical evidence, not just questions of faith. Once deities have been shown to exist by the preponderance of physical evidence, then one can ask for the physical evidence that they created life.
